Electronic commerce, or e-commerce, is the buying and selling of products or services over the internet. People can shop online through websites or apps instead of going to a local store. You can browse through the items, place an order, and even pay for everything from your computer or phone. For example, when you shop on websites like Amazon or any other online store that is e-commerce, it allows the companies to sell products to people all over the world without the need for a local store.
